Julian Casablancas, lead singer of The Strokes, performs before a crowd of about 3,500 screaming fans Saturday night at KFMA Day 2006 at the Tucson Sports Park, 6901 Casa Grande Highway. This is the seventh annual all-day music festival held by local rock station KFMA-FM, and it was billed as the largest outdoor concert in Tucson.
